HIV-1 seroprevalence rates in women attending prenatal clinics in Kampala; Uganda

ABSTRACT

The objective was to determine the HIV-1 seroprevalence in expectant women in Kampala. HIV-1 antibody status (by ELISA -Cambridge Biotech; with comformatory ELISA-Wellcozyme on positives); obstetric and socio-demographic characteristics were determined on a random proportionate to-size sample of 1002 expectant consenting women seeking care at 11 prenatal units in Kampala between august and December of 1993. HIV-1 age-specific rates were determined. Chi-square analysis; tests for linear trend in rates and 95CI were used to determine significance of seroprevalence rates. Results showed overall seroprevalence of HIV-1 for the study population (mean age = 22.4 years; range = 14 - 42 years) was 20.5(95CI18.0; 23.1); with the highest age-specific rate of 28.55 occurring at 20 - 22 years. An increasing trend of rates was observed between 14 - 24 years (p0.0001); followed; thereafter; by a decreasing trend (p
